For this week, Decision Science News has created a video tutorial on how to get started using the R Language for Statistical Computing. (The tutorial is best viewed in your browser’s full-screen mode, try pressing F11 in Windows). R is free and open source, and constantly being improved upon by countless contributors worldwide. DSN highly recommends using R.

Topics covered include:

  • Downloading and installing R in Windows
  • The R graphical user interface
  • Viewing the graphics demo
  • Vectors and basic stats
  • Simple plotting

The commands in the tutorial are:
demo(graphics)
x=c(1,2,3,4,5,6,7)
y=c(10,14,20,18,16,15,10)
x+y
z=c(x,y)
sum(y)
mean(y)
sd(y)
plot(x,y)
barplot(y,col=”lightgreen”)
